Definitly easy to do. I think theres a DIY guide for tappet adjustment that may have a guide to taking all the stuff (not sure). But definitly shouldnt be a problem at all

Bit fiddly, have to pull the intake manifold off. Only really need 10mm, 12mm & 14mm sockets & spanners thou...

there is actually a specific tightness for the torque bolts which is different for every car. in order to get them to the right setting a special 'torque wrench' is supposed to be used.

although it's not ideal, if you don't have one just tighten them as you would a normal bolt.

ok but im the type with bolts i pull with all my strength until it simply wnt budge anymore...thats the thing so how tight would you say like untill a good tug or to wnt tigthen it nymore or?

don't tighten it with extreme force, just tight enough so that it wont move around. a few hard tugs should do it.(no pun intended

lol)

The rocker cover bolts dont really need a torque wrench to be done, just dont crazy, judge by the size of the nut, bolt, screw.

i thought u were talking about the head gasket. lol

the rocker cover is just the tiny bolts that hold the two pieces of the head together, just tighten them like any other bolt, it's not overly drastic.

Most bolts on the car have a specific torque setting. To be honest, I never bother with an intake manifold. A hard nip up should be enough - just dont go popping a vien in your forehead....thats too tight.

FYI - if you had a torque wrench

The intake gasket is a dry gasket, so you should not be using any goo. If goo has been used, then strip it off & put a new gasket in. Using a razor blade as a scraper is sufficient, just try not to get any scrapings in the lower section of the intake manifold - as that'll result in it going thru the valves into the chambers. I usually jam a rag in each manifold port & vacuum them before removing them.

The gasket is only available from Mitsubishi - but dont worry, they are cheap as they common to the HJ galant. Part number is MD175776.

The rocker cover gasket itself is made of cork. You dont need to use gasket goo, but I find it handy to use some Hylomar to hold it in place on the rocker cover. Again, you'll need to clean the surfaces, but not nearly as critical as the intake manifold that you need to remove before you get to the rear rocker cover. Part number is MD309002.

When tightening the rocker cover itself, go very carefully. As mentioned, its a cork gasket, you only need to hand nip up the bolts. If you pull them up too tight it will split.

thanks a lot bennoz that helped a lot mate! do ineed to change the intake gasket though?or is that just in case i rip it when its coming off?does the throttle body need to come off the intake when removing the intake? im just going to see if i can get a torque wrench wanna be safe i guess...also while im tehre should i cahnge the fuel filter and rear spark plugs?

oh yea and i had a look before the rocker cover gasket is rubber...it looks liek its en changed before with a aftermarket one...

torque wrenches are expensive and a lot bigger then a normal wrench.

i got a torque wrench from super cheap for about $35 and its been brillant. no you only need to replace it if it breaks. If you dont know when they were changed definitly do the fuel filter and check the plugs

You dont need to change the inlet gasket. The throttle connected to the inlet so disconnect the intake pipe you can leave the throttle bosy connected. When you losen the bolts by feel you would be able to judge how tight to tighten the bolts. You could just tighten the bolts more this could stop the gasket leak.

One thing everyone if forgetting is, the timing cover is meant to come off and thats a pain in the arse to take off.

^ What they all said!

But will add that if you put all your force behind the bolts doing them up, you're likely to strip the thread. That would be BAD. Don't go crazy, just firm/tight.

hey all ok so i got two rocker cover gaskets coming from mitsubishi aus 60 dollars each. I also bough some top gun leads and some platinum spark plugs for 12bux each from autobarn he said they dont make irridums for the fto and its not listed anywhere....
